Abstract
1,243,046. Colour photography. INTERNATIONAL POLAROID CORP. July 23, 1968 [July 24, 1967], No. 35134/68. Heading G2C. Photographic colour process comprises (i) forming an imagewise distribution of a silver complex by development of an imagewise exposed silver halide emulsion, (ii) reacting the imagewise distribution with a material to alter the diffusibility of the latter and thereby form an imagewise distribution of diffusible colour-forming material, and (iii) forming a colour transfer image as a result of the preferential diffusion of the diffusible colourforming material. In a first embodiment, the material is a diffusible dye which is rendered non- diffusible by reaction with the silver ions or complex (e.g. a dye containing an anti-fogging moiety) and is situated either in the silver halide emulsion layer, or in a separate layer in the same or different material, the distribution being transferred to this layer by silver salt diffusion. The dye used in the emulsion layer may, if necessary, be rendered photographically innocuous by complexing, e.g. with a Zr salt, and the colour of the transferred dye may be altered, e.g. by treatment with a metal salt. In another embodiment there is similarly used a non-diffusible dye which reacts with the ions or complex to release a diffusible dye. Reference is also made to the use of materials which, on reaction, release a colourless colourformer which is subsequently coloured.
